Patent number: 8662276Abstract: A braking apparatus for a vehicle, in particular a heavy goods vehicle, includes a drive axle having a transmission gear, such as a differential, around which an amount of oil for lubrication is variable. The brake apparatus further includes at least one friction brake and at least one retarder that is capable of operating to slow the vehicle through the transmission gear. The braking apparatus comprises a brake operating device for operating the at least one friction brake and the least one retarder, and a determining feature to determine an oil level around the transmission gear. The brake operating device, on operation by a user, is arranged to apply the retarder when the oil level around the transmission gear is above a threshold level, and, if the oil level is below the threshold level, the brake operating device is arranged to initiate an increase in the oil level around the transmission gear.Type: GrantFiled: November 3, 2011Date of Patent: March 4, 2014Assignee: Meritor Technology, LLCInventors: Ralf Leiter, Roberto Gianone, Marco Fratelli, Marco Bassi, Chiara Cesari, Fabio Santinato, Clemente Magnago, Jon Honig, Karthik Kayyar, Juchirl Park, Cesare Bonfa

Patent number: 8469852Abstract: A transmission system includes a housing having a sump. A crown wheel and pinion are positioned within the housing. The transmission system further includes a reservoir having an inlet system and an outlet system. Rotation of the crown wheel causes the oil to be transferred from the sump to the reservoir via the inlet system, and the outlet system allows oil to pass from the reservoir to the sump.Type: GrantFiled: March 15, 2010Date of Patent: June 25, 2013Assignee: Meritor Heavy Vehicle Braking Systems (UK) LimitedInventors: Roberto Gianone, Chiara Cesari, Marco Bassi, Marco Fratelli, Clive Harrup, Bradley Arnold

Patent number: 8360915Abstract: An axle has a central crown wheel receiving portion with a pinion side and an opposite side. The opposite side is defined by a first crown wheel bowl for receiving a part of a crown wheel, the first crown wheel bowl having a peripheral edge. The axle includes a second crown wheel bowl for receiving the part of the crown wheel. The second crown wheel bowl is nested with the first crown wheel bowl and is attached to the first crown wheel bowl at a peripheral edge to define a reservoir.Type: GrantFiled: June 28, 2010Date of Patent: January 29, 2013Assignee: Meritor Technology, Inc.Inventors: Roberto Gianone, Chiara Cesari, Marco Bassi, Marco Fratelli, Stefano Martinello
